Atoms, molecules & ions

Module 2 focuses on matter at the microscopic chemical level: atoms, their variant isotopes and ions, and the molecules they form by combining. We'll take a brief tour of the history of atomic discovery and learn how atoms are built and how molecules are formed and named. Supporting material is found in Flowers et al., Chapter 2.
